Hi !
I am trying to run a Fast Fourier Transform on the signal you see on the picture (red).
And I cannot have more samples of the signal.
So, I applied a butterworth and got the blue signal. I am expecting a peak around 1500 Hz (the supposed frequency of the blue signal) ... but I do not obtain that(at all:bang.
I also tried to do a "zero-padding" but it think that it changes to much the initial spectrum.
Anyone have an idea to get ride of this noise or reducing it largely ?
Thank you for your help !
